I have water leaking in at the top of my 89 300TE liftgate and am 99% sure it is the liftgate seal. I am not sure if I should be posting this here or somewhere else since I know what the issue is, but I need to know.....

Who sells or does someone know the part number for the liftgate seal? not the windows seal, but the actual lifegate seal.

I have checked all the usual places, starting with the Pelican Parts store but all I can find is the front and rear doors.....no liftgate.
